To all whom it may concern:- Beat known that I, EL'MER F. Esrns, a

citizen of the United States,- residing at "Lincoln, in the; county of Lancaster and State of Nebraska, have invented new'and useful Improvements in .Borlng'f'o'n Excavat ingApparat'us; of-W'hich the following isa specification.

This invention relates to means for boring 01" excavating the earth for the reception of piles or other bodies, the'prim'a ry object of the invention beingto provide 1Tl2lIISWllFB-' by piles or other ob ects of wood-concrete or other vmaterials may be driven or sunk :within'; orv as -.part*- object to be embedded;

into;the earth to a desired or lnaxiinunr dept-h Without injury IHHD'I-"PBI lOCl of time, and; also Withoutthe and within a mini the excavating means necessity of forming of the pile" or other A- furtherobj-ect' of' theinvent-ion isto' rovide meanswhereby-the here may be formed and simultaneously flushed to remove the excavated material; so as to prevent such I material" front packing -or adher- ,in'g tethe pile or other'ob eot and. causing a resistance to lts 'deseent ;anda1set0'pro videexcavating 1 tools, or devices which 'lllfiiy be inexpensively ,censtmtedy Standard materials,"

.The invention consists of the features of construction, combination and arrangement of pairts hereinafter; fully descr bed and claimed, reference being hadre'theacconn panying drawings, in which Figure 1 is view showing:

g-devic'e applied theretof devices. Referring: to the shown= applied rny improved {hydraulic bor ing and flushingdevices g-; As{shown,the her ing device comprisesa prpe or conductor 2 extending-in p'a rallehre'latron tofthe pile. and

prt'nlided at its lower end. with a lateral extension 3 prefera-bljr'connected therewith by anortlinaryb-coupling 45; TheeX-tensmn 3 carries a delivery onbormgnozzle formed drawingd l designates fitted into the lower e'nd thereof and apointed plu'g- 7 fitted into the upper end there- .p'ile to supportthe nozzle ,below' and in ad Vance of} the pile forthe excavating action. The upper endof the pipe or conductor Qis source ofsupply of Water underthe requiredpressure. 'Fo'rflthe purpose of maintainingit-he' pipe or conductor in'proper position' relative tothe pile, a ropeor other suitable lashing 8 is employed in connec tion'ivit-h"anadjustable stop 9 on the pipe. This'st'opconsists of a sleeve adaptedto be secured in position by a set screw 10 and to the useiof this adjustable stop a conflductgnr ofa-ny-suitable length may be einployed and the stop positioned-fin seeuring the sa'lne to any length of pile. i

In practice a pile'fitt'ed with the boring or excavating device, through which-ajhyis lowered untilit cmnes'in contact with the bedded, in "which position it is maintained of water is then forced through the pipe and Will 01ft into the earthbelow the pile and "form ,an'eXcavati'on in"whichthe pile will sink under its own weight until, if. the pile be of wood, it. is: buoyed or supported-by the body" of water of the-stream, afterwhich wveiglitfiiiav be applied t'o the pil'e'to force it down untilei'nbeddedEto the desireddepth;

In Figs. land 2 l have shown the flushing pipe -proiided' with a flushing head of approximatelysemi-circular form and conunited to the flushing pipe by a: con'vontonal form of 'coupl1n'g.'- A plnra'litv of superposed heads of this'typemay be "em-- of,-whicl 1"plug is adapted to form an anchor" and to'bedriven into the lower tend of the designed in practice for .a ttaeln'nent to "any-,

of a T-coupling 5 having a nozzle proper 6 foosisting of: curved perforated pipe sections 'ployed, as shown in these views, or a single flushing'head may be used, as shown in Fig. 4, depending upon the amount ot'wat'er r'equiredtofiu sh the-bore underdilicrent con-.

ditions. A single flushing device having any suitable number of flushing heads of proper form and construction or two or more flushing device's, the use of two or more flushing devices the flushing heads may be of a formand so arranged as to encircle the pile, as illustrated 1n- Figs. 1 and 2. lVhere'the-pile or other object to be driven is of square or rectangular form in cross section, the flushing pipe 11 may be provided with a V-shaped or other angular form of flushing head 12, as shown in Fig. 5 or in the use of the device in connection with piles or objects of differ- I lodged by the excavating device. The bore is thus cleared of the excavated material, thus preventmg such material from choking the bore or adhering to the pile or object and' causing a resistance to its descent. The use of this flooding device is especially desirable and valuable in driving piles or other bodies through sand or silt, which tends to pack under and about the pile, and also facilitates the sinking of piles and other objects" in earthy matter of all kinds.

After the pile or object is en'ibedded to the desired depth, the flushing device is de tached andv pull it up, after which the pipe 2 is tapped with a hammer or other tool'with sufficient force'to loosen the ai'n-horing point 7, when the'pipe is turned by a suitable tool to bring the nozzle to a position clear of the pile, whereupon the excavating device may be readily and conveniently withdrawn.

By the use of my improved hydraulic excavating and flushing devices, wooden or concrete piles. or other bodies of these and other materials. may be driven or sunk into the earth above or below the surface of water ina ready, quick and convenient man- 1 er; and by supplying a concentrated jet of water through ithe c mating l /Alt, at high pressure, earth .cfany (harm-himpenetrable by'a liydra lirl.. rapidly excavated at a great yav and labor over the ordinary i chanically driving the by the use of my i wooden, concrete and (s ltcl. I .1- 1.01m lllllllmlllts e1 similar obiccts may be used, and in may be embedded without injury thereto. Another advantage of my nvention resides in the fact that the. appliances may-be used 4 in connection with existing and conventional types of piles and other objects without the necessity of specially constructing such piles or objects for the purpose orof making the hydraulic excavating means as a part of the pile o-robject itself. Preferably'the devices are so constructed that they "may be made of standard pipes and fittings, with resultant economy, p
